Sub-Bragg Phenomena in Multilayered Vibroacoustic Phononic Metamaterials
Majdi O. Gzal, Lawrence A. Bergman, Kathryn H. Matlack +1
Beyond classical Bragg diffraction, we report on new sub-Bragg phenomena to achieve enhanced sound wave tunability in the low-frequency range in a multilayered acoustic metamateria…
